Benefits of technology

[0006] The present invention has been achieved to solve the problem, and an object of the present invention is to provide a running toy comprising a steering mechanism which is easy to assemble and causes a little power transmission loss.
[0011] Accordingly, since the power of the DC motor for steering is transmitted via the clutch mechanism and the pinion and rack mechanism, the number of the elements can be reduced in comparison with the above conventional technique. Consequently, the assembly of the elements becomes extremely easy. Moreover, the power transmission loss can be reduced by the reduced number of the elements, enabling to perform steering with low power.
[0013] Accordingly, since the steering wheel and the DC motor for steering are provided at a position in front of a position of the steering arm of the vehicle body, grounding property of the steering wheel can be improved by the weight of the DC motor for steering, enabling to stably perform steering.

Problems solved by technology

Thus, there have been problems such as that the assembly of the elements is complicated and the power transmission loss is large.

Embodiment Construction

(Whole Structure of the Embodiment of the Present Invention)

[0029] FIGS. 1 to 3 are plan views of a running toy 100 of the embodiment of the present invention, wherein FIG. 1 shows a straight ahead state, FIG. 2 shows a left turn state, and FIG. 3 shows a state where steering wheels are moved forward and adjusted. In the explanation below, a back and forth direction of the running toy to go straight ahead is defined as a Y axis direction, a right and left direction is defined as an X axis direction, and a vertical direction is defined as a Z axis direction. These are at right angles with one another.

[0030] As shown in FIGS. 1 to 3, the running toy 100 comprises right and left rear wheels 21R, 21L as a drive wheel, right and left front wheels 22R, 22L as a steering wheel, front wheel support mechanisms 30R, 30L to support the front wheels 22R, 22L, respectively, a steering mechanism 60 to perform steering of each of the front wheels 22R, 22L, a running mechanism 80 to give running...

Abstract

A running toy having: a direct current motor for steering which is remote controlled; and a steering arm to change a direction of a wheel, the steering arm being operated from side to side with respect to a vehicle body by a power of the direct current motor for steering, wherein a rack tooth is formed on the steering arm, the direct current motor for steering is allowed to perform a normal rotation and a reverse rotation, and a pinion gear which meshes the rack tooth is attached to a shaft of the direct current motor for steering via a centrifugal clutch.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a running toy comprising a steering mechanism which is easy to assemble and causes a little power transmission loss. [0003] 2. Description of the Related Art [0004] Conventionally, as a steering mechanism of a running toy, there has been known one in which a power of a direct current motor for steering is transmitted through a clutch mechanism, motor pinion gears, crown gears, idle gears, sector wheels, an operation rod, and an operation member to actuate a steering arm from side to side with respect to a vehicle body (for example, refer to JP-Jitsukaihei-1-159893). [0005] However, in the above conventional technique, the structure is such that the motor power is transmitted to the steering arm through many elements. Thus, there have been problems such as that the assembly of the elements is complicated and the power transmission loss is large. SUMMARY OF THE INVENTION [0006] The pre...
